libfox-ruby or fxruby

Hi list
I want to learn ruby and use gui too.
That fore I want to use the fxruby (in the debian Tree it is called
libfox-ruby)
Unfortunately I haven't found a package for x86-64.
So I tried to build it my self.
I added this lines to source.list
....
deb http://freeride.rubyforge.org/debian/ deb/
deb-src http://freeride.rubyforge.org/debian/ src/
....
Because of the build dependencies I have to build fxscintilla-1.55
But during running
"dpkg-buildpackage -b -uc -rfakeroot"
I get the error, that the FOX libs are not found
".....
checking for fox/fx.h... yes
checking for FOX library... no
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no

The strange think is I already have installed
libfox1.0 und libfox1.0-dev
" dpkg -l libfox1.0

Do any one had installed it successfully?
Or have anyone a tip what is wrong and I can do?
